Someone once said cake is like a bad relationship. It woos you with sweet nothings and leaves you unsatisfied and guilt ridden. I think this is an excellent anology. I would go one step further and say Sugar is like an abusive relationship. There might be a moment when things are great but it is very detrimental to the person. The pleasure is momentary and afterward the person is left feeling empty, and not very good about themselves. Think about what you would tell your best friend if you knew they were involved in a relationship that was harmful and ultimately could cause them physical harm. What if they told you " I can't help it. I'm in love."
Now think about your relationship with food. Are you that abused person? How long will you allow yourself to stay in the situation?
